BACKGROUND OF INVENTION

As business grows more reliant on high-technology, the need for accurate and precise calibration and measurement becomes more imperative than ever. It is desirable to have standards and measurements that are directly traceable to NIST, and to have calibration and test program meet the highest standards of government and industry. Metrology laboratories may also be accredited by such programs as the National Voluntary Laboratory Accreditation Program (NVLAP).

A metrology laboratory might offer acceptance testing, calibration and repairs for instrumentation and standards in a wide array of discipline. Preferably, the metrology laboratory will issue certificates of calibration which can, when required, include as-found/as-left value and measurement uncertainties. A metrology laboratory may be able to calibrate equipment for measurement of temperature, humidity, mass, dimensional, pressure and vacuum, gas flow, force, torque, vibration, electrical, and time/frequency.

A metrology laboratory may also seek to provide complete calibration program management, including recall notification, interval management, reverse trace ability, procedure development, and records management.

A typical process for calibrating a unit under test (“UUT”) for a specific calibration function, is to connect it to a known pre-calibrated source having greater accuracy than the UUT, and then lead a putative measurement on the UUT. At the option of the meteorologist, the UUT may then be left as is, merely recording the as-found measurement against the reference output, or optionally adjusted so that the measurement on the UUT matches within appropriate limits the reference. It is possible to independently measure each range of a UUT against a standard, and record the as-found/as-left measurement.

The heart of the metrology laboratory calibration process is the calibration report, generally referred to a data sheet, of a UUT. Typically a data sheet resembles a spreadsheet, with rows containing range data, and columns representing fields. Data sheets may be constructed for specific manufacturer's equipment, for example a Flukes® 787 process meter, which contain one row for every function of the UUT to be tested. Functions might include, for example, testing in different voltage ranges corresponding to different dial or switch settings on the UUT. Once a data sheet is determined for that particular make and model, e.g. the appropriate functions are identified and fixed, the data sheet may be saved as a template and can be reused for all UUTs of identical make and model.

In the prior art, a data sheet of calibration data for a particular UUT would typically be saved on an array data structure basis, with one or more identifier such as UUT serial number, ID number, test number, etc., serving as a database index field for the entire test of that UUT. This can be implemented in simple spreadsheet format that can be done by hand, or by using computerized spreadsheet programs such as Microsoft Excel®, or other available programs as will be known to those skilled in the art.

Data saved in an array structure, however, is difficult to maintain, and no easy solution exists for the identification of particular functions (e.g., individual rows in a data sheet) that may need re-calibration or different calibration intervals. Further, no easy solution exists for setting calibration intervals based upon drift analysis rather than failure based tolerance. Also, current data sheet based testing makes it difficult to tie standards to test points and calculate accuracy ratios for individual functions.

What is needed is a way to identify individual functions of a UUT, cross-link standards with these functions, and identify test points that may be problematic. Preferably, such a solution would optionally allow for simultaneous testing of like UUTs, and additionally optionally provide a comprehensive software tool that can augment a current system in place in an existing metrology laboratory, which simplifies and speeds up actual calibration process. Preferably this software tool would optionally perform multiple calibrations, reduce turnaround time, maintain a datasheet library, automate calibrations, calculate tolerances and analyze uncertainties.

SUMMARY OF INVENTION

The present invention meets this need by providing a way to identify individual functions of a UUT, cross-link standards with these functions, and identify test points that may be problematic. A method is disclosed for simultaneous testing of like UUTs, and a comprehensive software tool is described that can augment a current system in place in an existing metrology laboratory, which simplifies and speeds up actual calibration process. This software tool can perform multiple calibrations, reduce turnaround time, maintain a datasheet library, automate calibrations, calculate tolerances and analyze uncertainties.

A method for calibration process management of a calibration testing unit and a plurality of units under test is disclosed comprising configuring a user interface in communication with a calibration process management software system; configuring a communications link in communication with the software system, the software system capable of communicating with the calibration testing unit and the plurality of units under test; and wherein the software system manages the user interface and the communications link in a manner permitting an operator to calibrate the plurality of units under test.

Tracking of the calibrated units under test uses a permanent unique identifier and a dynamic unique identifier. Each permanent unique identifier is assigned when an object is created or altered in a manner that would make it unlinkable to its past usage, and each dynamic unique identifier is assigned any time the object is modified or saved.

A system for calibration process management of one or more than one unit under test (UUT), each UUT being an instance of a UUT equipment type is disclosed comprising a first computer readable medium for storing one or more first data objects representing calibration data from the one or more than one UUT; a second computer readable medium for storing a first globally unique identifier in an association relationship to one of the one or more first data objects; a third computer readable medium for storing one or more second data objects representing a reference standard for the UUT equipment class; a fourth computer readable medium for storing a second globally unique identifier in an association relationship to one of the one or more second data objects; a calibration management control program embodied on a fifth computer-readable medium for calibration of the one or more than one UUT, the calibration management control program in communication with the first data objects, second data objects, first globally unique identifier and second globally unique identifier, and an application program interface embodied on a sixth computer-readable medium for execution on a computer in conjunction with the calibration management control program.

The calibration management control program further optionally permits contemporaneous calibration of more than one UUT, and the application program interface is configured for contemporaneous calibration of more than one UUT, each UUT being an instance of the same UUT equipment type.

The application program interface can be configured to receive identification of the UUT equipment type, and a value as found for a specific calibration function, and display tolerance limits for the UUT based upon the UUT equipment type.

A method for calibrating a UUT for a specific calibration function is described comprising the steps of receiving a first identification attribute associated with a UUT; receiving a second identification attribute associated with a reference measuring unit; receiving a specific calibration function to be tested; maintaining in a first memory a reference database of one or more than one second identification attribute in holding relationship to one or more than one reference identification address, each reference identification address being associated with a single calibration function; looking up in the reference database, the reference identification address being held by the second identification attribute, and associated with the specific calibration function; selecting a unique record identification address; receiving a value as found for the specific calibration function for the UUT; storing in a second memory the value as found in a being-held relationship to the record identification address; and storing in a third memory the record identification address in a being-held relationship to the reference identification address. Further, either the first identification attribute or the second identification attribute, or both the first identification attribute and the second identification attribute, may be an asset number.

Optionally, the steps of receiving a value as left for the specific calibration function for the UUT and storing in the second memory the value as left in a being-held relationship to the record identification address may be added. A test accuracy ratio may be returned. An estimated measurement uncertainty may be returned. The step of automatically converting the units of the received value as found may be added.

Further, steps may be added of maintaining in a fourth memory an equipment database correlating for individual make and model of equipment, a nominal value to calibration function; receiving make and model of equipment attributes for the UUT; looking up in the equipment database, the nominal value for the specific calibration function for the received make and model of equipment; returning the nominal value; and calculating a calibration tolerance and returning the limits. Still further steps are receiving a value as left for the specific calibration function for the UUT and storing in a fifth memory the value as left in a being-held relationship to the record identification address. The value as found or the value as left is within the limits of the calibration tolerance may be indicated.

DETAILED DESCRIPTION

Using the calibration process management system (“CPMS”) of the present invention, it is possible to create, manage and automate data sheets for the calibration of measuring and test equipment. The system has multiple tools to facilitate the translation of equipment specifications into electronic data sheets. These electronic data sheets can then be used to collect and store calibration data for a plurality of instruments simultaneously. Automation scripting can be added to these data sheets to configure instruments, capture data, perform mathematical operations, communicate with external software, and create instrument test points dynamically. While instruments are being tested, the invention can indicate the degree to which an instrument is in or out of tolerance.

A system using the present invention can be developed to satisfy ISO-17025, ANSI/NCSL 2-540-1, 10 CFR 50 Appendix B, ISO-9002, GMP, and other stringent quality requirements for calibration data collection.

In one preferred embodiment, the following assumptions are made regarding the system implementation and operation: (a) the software will run in a Windows 95 or higher environment, and (b) connection to a database server running Microsoft SQL Server version 7 or greater. Alternative environments and database servers are possible, as will be evident to those skilled in the art. To run automation scripts that use GPIB communications, a National Instruments GPIB controller card, or equivalent, may be required.

The CPMS of the present invention creates, manages, and automates data sheets, and analyses collected data. The system has multiple tools to facilitate the translation of equipment specifications into electronic data sheets. These electronic data sheets can then be used to collect and store calibration data for multiple instruments simultaneously. In one preferred embodiment, eight instruments can be calibrated simultaneously.

Optionally, automation scripting can be added to these data sheets to configure instruments, capture data, perform mathematical operations, communicate with external software, and even create instrument test points dynamically. While test point data is being collected, in a further embodiment, the CPMS according to the present invention will indicate the degree to which an instrument is in or out of tolerance.

System Description

One embodiment of the CPMS of the present invention will now be described. It will be understood by those skilled in the art that variations in the described embodiment are possible, and that specific aspects of this embodiment are not limitations on the claimed invention. This CPMS, with reference to FIGS. 80 and 82, comprises a calibration process management program 10 (one embodiment being the “Calibration Process Manager”) which is stored on a hard drive memory 54 of a computer 52 which is connected to a calibration testing unit 56, and one or more units under test (UUT) 58. It is possible to have multiple UUTs 58 connected and tested using the present invention. Optional printer 60 permits printing of data sheets 62. An appropriate user interface on computer 52 is needed for operator interaction with the calibration process management program 10. As described herein, an appropriate communications link is established between the calibration process management program 10, the calibration testing unit 56, and the one or more units under test (UUT) 58. A series of pages and prompts as will now be described will appear on the user interface on computer 52, guiding an operator to calibration of the one or more units under test.

The first time the Calibration Process Manager is run, a Database Server Page as shown in FIG. 1 will appear to prompt the user for information that it will use to connect to the database server. The database server page can also be accessed by using the Administration, System Configuration, Database Server menu option. Changing database server settings requires the Calibration Process Manger to shut itself down. Calibration Process Manger will connect using the new settings the next time it is started. This page contains the interface features in Table 1.

FIG. 2 is a representation of a Master System Configuration Page for the CALIBRATION PROCESS MANAGER The Master System Configuration page is accessed by using the Administration, System Configuration, Master Setup menu option. This page contains the interface features shown in Table 2.

In a further embodiment a sound configuration page allows the user to set up sound clip options that are used with the Calibration Process Manager application. FIG. 3 is a representation of what a sound configuration screen looks like.

The Calibration Process Manager provides a secure environment along with an audit trail to track changes to the system parameters as well as archiving of records. The security setup procedures of the Calibration Process Manager are performed by a user with System Administrator privileges. When the system database is initially installed a single user exists in the system, SysAdmin. The System Administrator performs the initial setup for the Calibration Process Manager, will login as SysAdmin and proceed to configure the system in preparation for use throughout the organization. System users must be setup prior to using the Calibration Process Manager. These users will be given the default set of permissions, once they are created. The System Administrator will adjust the user's permissions as required. FIG. 4 is a representation of what the System Login Page looks like.

The System Login page is displayed when the Calibration Process Manager application is run. If the user fails to login, the application will terminate. This page contains the interface features shown in Table 3.

FIG. 5 is a representation of what the User Manager Page looks like. The User Manager page is accessed by using the Administration, User Manager menu option. System Administrator privileges are required to access the User Manager page. The User Manager page displays the master list of users for the Metrology suite of applications. All of the applications share a common user database. This page is the starting point for viewing, editing, and creating user accounts. The page also provides the gateway to user permissions, changing a user's password, and setting up the system's default login rules. This page contains the interface features in Table 4.

FIG. 6 is a representation of what the User Login Rules page looks like. The User Login Rules page is accessed by the Set Default Login Rules button on the User Manager page. This page is used to setup the system's basic security rules including user login rules. This page contains the interface features in Table 5.

FIG. 7 is a representation of what the Create a New User Page looks like. The Create a New User page is accessed by clicking the New User button on the User Manager page. The page is used to setup a new user account. This page contains the interface features in Table 6.

FIG. 8 is a representation of what the Edit User Login Page looks like. The Edit User Login page is accessed by clicking the Properties button on the User Manager page. The Edit User Login page displays and permits editing of the basic account information for the currently selected user.

FIG. 9 is a representation of what the User Permissions Page looks like. The User Permissions page is accessed by the permissions button on the user manager page. The User Permissions page is used to manage a user's privileges within the Calibration Process Manger. This page contains the interface features in Table 7.

FIG. 10 is a representation of what the Change Password Page looks like. The change password page can be accessed by two methods. The first is with the Options, Change Password menu option. The second is with the Change password button found in the User Manager page. However, with the Options, Change Password menu option, the user will have to input the current password. The Change Password Page contains the interface features in Table. Passwords cannot be less than six characters in length, or more than fourteen characters in length. They must be alphanumeric, and cannot match the login ID for the user.

FIG. 11 is a representation of what the Audit Report Page looks like. The Audit Report page is accessed by the main form's Administration, Audit Report menu option. The Audit Report page is used to setup, save, load, and execute Audit Report configurations. This page contains the interface features in Table 8.

FIG. 12 is a representation of what the main screen of the Calibration Process Manager application looks like. The main page is the screen that the Calibration Process Manager application opens to. The common thread of the Calibration Process Manager application is that it graphically represents, and is navigated as, a data sheet. It will display information as it is collected and auto format the test result columns to ensure each data sheet maintains a uniform look.

The main page has three master modes of operation: Data Sheet Designer, Data Collection, and statistics. When the application opens, the Master Mode is set to Data Collection. This page contains the interface features in Table 9.

Appendix B is a list of the menu options that are available in the Calibration Process Manager application's main page for one version.

A Master Mode selection drop down list allows the user to select what the current functionality of the application is to be. The choices are in Table 10.

FIG. 13 is a representation of what the Calibration Process Manger main page (Data Collection mode) looks like. The primary purpose of the Data Collection section is to facilitate the collection of measurement data and the design and execution of automation scripts.

Calibration Process Manager allows for the collection of data for more than one instrument simultaneously. This can be done, providing the instruments use the same data sheet. In one embodiment, up to eight sets of measurement data can be collected. As is evident, a system could be constructed for more or fewer sets. Each instrument under test is a “channel” and will display the “As Found”, “As Left”, and “Out of Tolerance” data. All eight channels can be displayed and edited simultaneously. These channels are activated and configured independently.

FIG. 13A is a representation of what a Calibration Process Manger Data Collection Channel looks like. A channel is container object that represents one of the units under test. When a channel is selected, its display is highlighted and measurement data is recorded into that channel. The channels display measurement data collected for the currently selected row of the data sheet grid. “As found”, “As left”, and “Out of Tolerance” information is displayed in relevant columns of the data sheet grid for the channel that is currently selected. These data sheet columns are not visible when editing automation script commands to preserve space. The script command list grid occupies part of the space normally reserved for the data sheet grid. The Tolerance column of the data sheet grid will display graphical status information for each of the active channels, as shown in FIG. 13A.

The active tabs displayed at the top of the main page indicate which channels are designated for instruments and which are currently active for testing. When the active check box is selected, the UUT Boilerplate Setup page is displayed. The UUT Boilerplate Setup page is where the unit under test information is configured for the selected channel.

A data sheet must be loaded prior to activating a channel. The Calibration Process Manager uses the data sheet as a template for data collection. All determinations of the nominal test point definition, in tolerance status, and Specification Tracking standards used are derived from the active data sheet. The measurement data collected for each of the channels is stored separately in memory and is not stored in the active data sheet. When a calibration is saved, exported to a file, or printed, The Calibration Process Manager merges the channel and data sheet data into a single calibration file. If a calibration is to be reopened or imported for further data collection, the applicable data sheet must first be loaded. If the active data sheet is not the same data sheet or same version of the data sheet used to create the calibration file, a warning message will be displayed.

When a calibration is reopened into a channel, all measurement data is reevaluated, using the data sheet's information. If the data sheet's nominal test point definitions or tolerances have been modified, the calibrations in tolerance status will be adjusted accordingly. For this reason, historical calibration records should not be viewed or reprinted from within a channel. To view, reprint or export historical calibration files, set the Calibration Process Manager's Master Mode to Data Sheet Designer or Statistics, then use the File, Open, . . . menu options to load the calibration. These modes do not interpret the measurement data, they merely display it.

An active data collection channel contains the interface features in Table 11.

In one embodiment, when a channel is active the Show Standards button will be visible at the top of the main page. If no standards have been assigned to the data sheet the circle will flash red. Once standards have been assigned to the data sheet, the light will show green. When the button is clicked into the depressed position, the standards fields will be displayed at the bottom of the screen. However, the data collection channels will not be displayed again until the Show Standards button is de-selected (returned to the up position).

FIG. 14 is a representation of what the UUT Boilerplate Setup page looks like. If the channel in which the active check box is selected has not previously been configured, then the UUT Boilerplate Setup page will be opened. The UUT Boilerplate Setup page allows the user to designate asset numbers, test numbers, and other information to units under test for each channel. The UUT Boilerplate Setup page contains the interface features in Table 12.

The Function Field contains four indicators. The first is the Timer indicator. This will display a numeric value of a delay period specified by a script command. It will count down until the delay is completed. The remaining three indicators, GPIB, OLE, and RS-232 will show one of four colors: gray for not is use, green for reading data, yellow for writing data, and red for error. These colors will be visible during the corresponding command execution. Warnings and errors will cause a Calibration Process Manager Warning window to be displayed indicating the possible cause of the error or warning. The script will be halted, When the user has corrected the error, testing can resume.

The Measured Value Radio Selection field contains two radio buttons. The options are for “As Found” or “As Left” data collection. This selection represents the master data collection mode. Only one radio button can be selected at a time they will activate the corresponding field on the channel display.

The All Cal Files section has the following four buttons: to copy “as found” data to “as left”, print, view the master boilerplate data, and save calibrations. The copy “as found” to “as left” function will copy the numeric value from one field to the other within the channel display. These buttons will cause their action to propagate to all open channels. The operation of these buttons is identical to their operation when selected on the individual channel boxes, with the exception of the view boilerplate data button.

The “Show:” Selection panel contains two check boxes. The tolerance check box indicates if the tolerance value will be displayed in the “tolerance” column of the data sheet. The percentage of tolerance box indicates whether or not the percentage of tolerance consumed will be displayed in the “tolerance” column of the data sheet. These options only affect how data is displayed, not stored or printed.

The Data Sheet Master Grid contains the per line information for unit tests. The Tolerance field is updated as the tests are executed giving a real time indication of the test values. These results will not be user editable.

When a measured value is recorded for an instrument channel, the system will compare the value to the instrument's Tolerance as set in the data sheet, indicate the “out of tolerance” status, then display the percentage of the tolerance consumed. This operation is only performed on test points that contain calculable data in the Nominal Value and Tolerance cells.

Data can also be collected by use of the automated scripting system. This allows data collection from a GPIB, RS-232, Custom User Prompts, or the result of scripted mathematical operations. The user can design and execute automation scripting for the current data sheet. The Data Collection page contains commands for executing, halting, and when the Script Commands are visible, editing automation commands.

The script is executed by pressing the Command Menu key on the QuickData Keypad, clicking on the run button, or pressing the F12 key on the system keyboard. When an interface command group (command menu item) is selected from the pop-up Command Menu, the application will attempt to run the scripted commands, sequentially, for the interface command group being executed. The system will, as necessary, open other command based forms to assist the user in executing the test properly.

The Calibration Process Manager main page (Data Sheet Designer mode) option gives the user the means by which they may create data sheets. These data sheets may then be used as a template for automation scripting and the collection of calibration data. A data sheet is the starting point for all operations within the Calibration Process Manager application. This section describes the tools available to assist in the data sheet creation process.

FIG. 15 is a representation of what the Main Form's Data Sheet Designer mode looks like. The Calibration Process Manger main page (Data sheet designer mode) contains the interface features shown in Appendix D.

FIG. 16 is a representation of what the Calibration Process Manger main page (Statistics mode) looks like. The Statistics page allows the user to easily view past test results for a particular data sheet. The results can be displayed for variable date ranges, and can be specific to the data sheet or the asset. The statistics page contains the interface features in Table 13. The test point history is displayed as: As Found—Blue Diamonds; As Left—Red Diamonds; Nominal Value—Black Lines; Tolerance Value—Red Lines.

FIG. 17 is a representation of what the Drift Analyzer Interface page looks like. The Drift Analyzer Interface page is accessed by clicking on the Analyze Drift button, when the Calibration Process Manager's main form is in the Statistics mode. This page requires that an instrument history performance analysis (IHPA) application be installed on the computer. A suitable IHPA application is currently marketed by CRS Engineering Inc. The drift analyzer interface page allows the user to save drift analysis data as a spreadsheet file, such as such as Microsoft Excel format, for use with the IHPA application. Typically, the IHPA is a spreadsheet application. Once the file is created the IHPA spreadsheet application is executed.

The Drift Analyzer Interface page contains the interface features in Table 14.

Drift analysis predicts new values based on previously collected data using a least-squares linear regression of a range of the known data or known x-arrays and y-arrays. For example, given corporate earnings for each of the previous six quarters, a drift analysis function returns earnings expected for the next two quarters. This is the same methodology used in “forecasting” techniques.

FIG. 17A is a representation of an interval analysis report. For calibration interval analysis, the term reliability refers to the probability that an item or parameter of measuring or test equipment (MTE) is in-tolerance. When items are periodically tested or calibrated, the observed reliability is the fraction of items observed to be in-tolerance at the end of the test or calibration interval. This is a binomial test, i.e., the item or parameter either passes or fails.

Testing the observed reliability R_(obs) involves comparing it against some established minimum acceptable in-tolerance confidence level, referred to as the reliability target R_(targ). With one method, the A3 Interval Method, the observed reliability is computed by simply dividing the Number of Tests into the Number In-Tolerance. For example, if the Number of Tests n for a grouping is 25 and the Number In-Tolerance x is 20, the observed reliability is 80%.

This test methodology works by comparing R_(obs) to R_(targ) to see if there is a significant difference between the two tests within the interval. The magnitude of the difference and the Test Confidence Level determine whether or not the difference is significant. If it is, then the interval corresponding to R_(obs) is said to have failed the test and a recommendation with respect to present interval is suggested (i.e., the interval will either be lengthened or shortened).

The algorithm used to test the interval evaluates whether upper and lower confidence limits for R_(obs) contain the reliability target. If so, then the interval passes the test. A preferred method for determining the confidence limits for R_(obs) uses a binomial distribution function. Given a Number of Tests n and a Number In-Tolerance x, the upper and lower confidence limits are obtained by solving a binomial confidence interval equation. If R_(targ) is within these limits, then the interval passes the test. If the interval is rejected, a new recommended interval is computed using a simple algorithm. The process takes place in two stages. In the first stage, the interval is adjusted to a trial value. In the second stage, the trial value is refined to ensure its feasibility.

Calibration Process Manager has two primary document types: data sheets and calibrations. A data sheet is essentially a template for a calibration. A calibration is a data sheet with actual measurement data recorded. Data sheets are actually much more than a simple template, as they may also contain complete automation scripting and detailed information regarding UUT and standard instrument specifications and uncertainties.

A data sheet is a pre-engineered template used to execute and record calibration data. Data sheets may also contain complete automation scripting and detailed information regarding UUT and standard instrument specifications and uncertainties.

FIG. 18 is a representation of what the Data Sheet Catalog Page looks like. The Data Sheet Catalog Page allows the user to locate and load a data sheet. The Data Sheet Catalog Page is displayed by selecting the File, Data Sheet, Open menu option. The catalog displays both data sheets and data sheet groups. A Data sheet group is a collection of data sheets established using the Data Sheet Group Wizard.

In one embodiment, the Calibration Process Manager does not have a database, consequentially it does not have a data sheet catalog. In that embodiment, it is therefore recommended that a shared network directory be used store and share data sheet files. Some degree of document control can be achieved by managing access rights to this directory. By default, the Calibration Process Manager will look for data sheets in the “DataSheets” directory of the path from which the application was run. If the application is stored in a “Read Only” directory on the local area network, the system administrator can create a “DataSheets” subdirectory. It is also recommended that a structured sub directory system be created inside the “ . . . \DataSheets\” directory to assist users in locating the appropriate data sheet.

The Data Sheet Catalog Page contains the interface features in Table 15.

An external data sheet file can be loaded into the Calibration Process Manager by selecting the File, Import, Data Sheet File menu option. The standard windows file location dialog is used to locate a file. Once loaded the data sheet is ready for editing, approval, or use in data collection.

FIG. 19 is a representation of what the Data Sheet Approval Page looks like. The Data Sheet Approval Page allows the user to approve a data sheet and enter it into The Calibration Process Manager's data sheet database. The Data Sheet Catalog Page is displayed by selecting the File, Data Sheet, Approve menu option.

The Data Sheet Approval Page also allows for other administrative functions including: Reactivating a previously inactivated data sheet, inactivating a data sheet, and deleting a data sheet. All of these administrative functions require the user to have System Administrator privileges. The data sheet must first be loaded into the Calibration Process Manger prior to activating the Data Sheet Approval Page. All of the actions taken on this page will require a special login of a user with data sheet approval or system administrator privileges.

The Data Sheet Approval Page contains the interface features in Table 16.

A Calibration Process Manager data sheet can be exported to an external data sheet file by selecting the File, Export, Data Sheet File menu option or the File, Data Sheet, (Save or Save As) menu option. The Standard windows file save dialog is used to set the file name and location. Working with files is the preferred method of saving a data sheet while it is being designed or edited. It should not be returned to the data base until it is ready for use in calibrations.

A Data sheet group is a collection of data sheets established using the Data Sheet Group Wizard. Data sheet groups are used to bind together a set of data sheets that are needed to calibrate an asset that may be comprised of two or more instruments. Once created, data sheet groups appear in the Data Sheet Catalog. Data sheet groups can be located in the Data Sheet Catalog using the same methods that would apply to a single data sheet. Once a data sheet group is selected using the Data Sheet Catalog, the user will be prompted to select a member data sheet using the Data Sheet Group Selector page.

FIG. 20 is a representation of what the Data Sheet Group Selector page looks like. The Data Sheet Group Selector page allows the user to select a data sheet from a data sheet group. The page is accessed from the Data Sheet Catalog Page. The Group Members button of the Data Sheet Catalog Page is enabled when a data sheet group is selected in the Data Sheet Catalog Page's data sheet grid. Click on this button to view the Data Sheet Group Selector page.

The Data Sheet Group Selector page contains the interface features in Table 17.

FIG. 21 is a representation of what the Data Sheet Group Wizard page looks like.

The Data Sheet Group Wizard page allows the user to create and edit data sheet groups. The page is accessed via the Tools, Wizards, Data Sheet Groups, New Group menu option to create a new group or the Tools, Wizards, Data Sheet Groups, Edit Existing Group menu option to edit an existing group. The features are in Table 18.

FIG. 22 is a representation of what the Data Sheet Group Approval page looks like. The Data Sheet Group Approval page allows the user to approve data sheet groups created or edited with the Data Sheet Group Wizard. The page is accessed by clicking on the Data Sheet Group Wizard page's Ok button upon completion of the data sheet group edit process. Features are in Table 19.

A calibration file is originated from a data sheet file for a unit whose measurement data has already been collected or is currently being collected. It retains and displays the measurement results and Specification Tracking standards used. This allows the user to save calibration information for units under test and cross-examine the results. The calibration file does not retain the automation or Specification Tracking default standard information of the data sheet. Calibrations can be stored in the system database for long term history or exported as a file for short term storage and transfer. In a more basic embodiment, calibration files do not contain any Specification Tracking data.

FIG. 23 is a representation of what the Calibration History Catalog Page looks like. The Calibration History Catalog Page allows the user to locate and load a Calibration. When in the Data Sheet Designer mode, the Calibration History Catalog Page is displayed by selecting the File, Calibration, Open menu option. When in the Data Collection mode, the Calibration History Catalog Page is displayed by clicking on the Open Cal button of the UUT Boilerplate Setup page. The UUT Boilerplate Setup page is accessed by clicking on the Set UUT Boilerplate button of one of the active UUT Channels. The data sheet used to create the calibration should be loaded into the Calibration Process Manager before loading a calibration. The data collection system uses the data sheet as a reference and the user will be warned if the applicable data sheet is not loaded first.

A basic embodiment of the Calibration Process Manager does not have a database, consequentially it does not have a calibration history catalog. It is therefore recommended that a shared network directory be used store and share calibration files. All users must have “Write” access to this directory. By default, the Calibration Process Manager will store calibration files in the subdirectories of the “Calibrations” directory of the path from which the application was run. If the application is stored in a directory on the local area network, the system administrator can create a “Calibrations” subdirectory. The Calibration History Catalog Page contains the interface features in Table 20.

An external calibration file can be loaded into the Calibration Process Manager. When in the Data Sheet Designer mode, the standard windows file locator dialog is displayed by selecting the File, Import, Calibration File menu option. Calibration files loaded in the Data Sheet Designer mode can not be stored in the database. The file must be imported in the Data Collection mode to be stored in the database.

When in the Data Collection mode, the standard windows file locator dialog is displayed by clicking on the Import Cal button of the UUT Boilerplate Setup page. The UUT Boilerplate Setup page is accessed by clicking on the Set UUT Boilerplate button of one of the active UUT Channels. The data sheet used to create the calibration should be loaded into the Calibration Process Manager before loading a calibration. The data collection system uses the data sheet as a reference and the user will be warned if the applicable data sheet is not loaded first. Once loaded the calibration is ready for editing or approval.

FIG. 24 is a representation of what the Search for File page looks like. This allows the user to look on the local system for a previously exported calibration file. This page will contain the information in Table 21.

FIG. 25 is a representation of what the Sign Calibration Page looks like. Calibrations can only be signed into the database when in the Data Collection mode and the calibration is in an active channel. When in the Data Collection mode, the Sign Calibration Page allows the user to sign a calibration and enter it into the Calibration Process Manager's calibration database. The user must have the calibration signature privilege assigned on the user permissions page. The Sign Calibration Page is displayed by clicking on the Save Cal button of the UUT Boilerplate Setup page. The UUT Boilerplate Setup page is accessed by clicking on the Set UUT Boilerplate button of one of the active UUT Channels. The Sign Calibration Page contains the interface features in Table 22.

A Calibration Process Manager Calibration and be exported to an external calibration file. When in the Data Sheet Designer mode, the standard windows file save dialog is displayed by selecting the File, Export, Calibration File menu option. When in the Data Collection mode, the standard windows file save dialog is displayed by clicking on the Export Cal button of the UUT Boilerplate Setup page. The UUT Boilerplate Setup page is accessed by clicking on the Set UUT Boilerplate button of one of the active UUT Channels.

FIG. 26 is a representation of what the Select Discipline Directory page looks like. The Select Discipline Directory page allows the user to export calibration files to a set of fixed discipline directories.

FIG. 27 is a representation of what the Data Sheet Print Shop page looks like. The Data Sheet Print Shop page allows the user to print data sheets or calibrations, and configure printers and page settings. The print button, in the Data Sheet Designer page accesses this page. The page can also be accessed by clicking on one of the Print buttons of an active calibration channel. The Data Sheet Print Shop page has the interface features in Table 23.

FIG. 28 is a representation of what the Document History Page looks like. The Document History Page allows the user to view the version history of data sheets and calibrations. To display the history of the document currently displayed in the Calibration Process Manager's primary data sheet display grid, select the Administration, Document History menu option. To display the history of a calibration currently displayed in one of the Calibration Process Manager's data collection channels, click on the Doc History button of the applicable UUT Boilerplate Setup page. The Document History Page contains the interface features in Table 24.

Data sheet design is performed when the Calibration Process Manager's main form is set to the Data Sheet Design mode. The electronic data sheets will be used to collect and store instrument calibration information. These data sheets will report the measurement data for instruments under test. Once approved for use, data sheets are stored in the system database. Data sheets can be saved as a flat file, with a .MDD extension, while in development or for transfer purposes. In one embodiment, a single data sheet will be able to collect and store calibration information for up to eight instruments simultaneously. It is possible to create a system for more or less units. The data sheets can be scripted to collect data from GPIB, RS-232, or custom user prompts.

The Calibration Process Manager application has different ways to create a data sheet, including manual entry (typing), the tolerance calculator, test point wizards, and data sheet generation wizards.

All Data Sheets will be automatically formatted to maintain a uniform look and feel from sheet to sheet. Calibration Process Manager will determine the necessary font size, spacing, and line splitting for each data column as entered. Each data sheet column has its own rules for formatting its content. The header row of each page also has formatting rules that differ from the data rows. Header rows are indicated in two ways: There cells are gray, and they are always on line number zero. The page and line numbers are displayed on the left edge of the data sheet grid. It is recommended that data sheet headers be inserted into data sheet last. As new rows are inserted into the data sheet, the rows containing the header information will be moved down. Once editing is completed, you will have to adjust your header rows. It is easiest to just delete header rows that are out of position and re-add add them to the first row of each page. The headers are inserted using the “Insert Headers” button. The “Insert Headers” button will insert the headers in the selected row and push the rest of the data sheet down one row. The “Insert Headers” function copies the header information from the first page of the data sheet. If you plan to use non-standard headers, change the first set of headers before using the function. While other data temporarily occupies the header rows, the text formatting will use the header row's formatting rules, but once the headers are inserted, the data will be pushed into normal data rows and assume proper formatting.

The Calibration Process Manager uses only ANSI standard characters within a data sheet. The main reason for this is universal data compatibility. Whether stored in the system database or exported to files, the information contained can be read and used by any application, on any operating system. Exported files are stored in a straight forward, tab delimited, text format so they may be used by other applications. If you decide to use something other than the Calibration Process Manager in the future, you can take your data with you.

There are only two special character flags used with the Calibration Process Manager's data sheet editor and they have the following meaning. The flag “˜” is a Forced Line Break. This character forces a line break wherever it appears. This overrides the internal automatic formatting of the data sheet editor. This is useful when it enhances readability of the data sheet. The character is not printed on data sheets or displayed in the data sheet grid.

The flag “˜@” is a Parametric Divider. These characters inform the Nominal Value decoder that what follows is another parametric value., i.e.: 190 mV˜@20 kHz˜@ 1 mA. When displayed the item will appear as: 190 mV@20 kHz@ 1 mA.

The decoder will interpret this as having three parametric values. The first parameter is used by to indicate the test point's nominal value. The Professional and Pro Remote versions will use all three parameters for the parametric matching of Specification Tracking Instrument Ranges. The “˜” character also serves its primary function of causing a forced line break. The decoder requires that each parameter have a numeric value followed by the units of measure. The decoder can resolve the parameters with or without spaces, but inserting the space between the value and unit of measure is easier for humans to read. There can be no space between the ˜ and @ characters. If the ˜ character appears by itself in the Nominal Value cell, it instructs the decoder to disregard it and anything that follows it. For printing and display purposes it will still serve its primary purpose of forcing a line break. Using the ˜ character by itself allows you to add additional text to the Nominal Value cell without confusing the decoder. i.e.: 190 mV˜@100 Hz˜(Slow Mode). When displayed the item will appear as: 190 mV@ 100 Hz (Slow Mode). The two parameters are recognized and the rest ignored.

FIG. 29 is a representation of what the Master Boiler Plate Data page looks like. The Calibration Process Manager Master Boiler Plate Data page allows the user to set header type information for the data sheet. This page also allows the user to configure system behaviors that apply when the data sheet is activated. The Master Boiler Plate Data page is activated by clicking the View/Edit Boilerplate button on the application's main page. The Boiler Plate Data page contains the interface features in Table 25.

FIG. 30 is a representation of what the Remarks Editor looks like. The Calibration Process Manager Remarks Editor allows the user to set global or per-line comments for the data sheet. The Remarks Editor contains the interface features in Table 26.

FIG. 31 is a representation of what the Data Sheet Operations Commands page looks like.

The Data Sheet Operations Commands page allows the user to set special data sheet directives that override normal data sheet behavior.

FIG. 32 is a representation of what the data sheet with the tolerance calculator looks like.

The integrated tolerance calculator allows a data sheet designer to generate test point row data by entering the nominal test point values and equipment specification data. The tolerance is calculated, formatted, and then the new test points are inserted into the data sheet.

The calculator uses a smart rounding system to appropriately round tolerance values. It will support both standard specifications, (% of I.V., ppm of I.V., % of F.S., ppm of F.S., ±n units of measure, and ±dB.) and custom specification calculators. The custom specifications contain more complex components (i.e. ±0.0025% of I.V., per volt above 750 volts). Custom specification calculators can be defined by the user, stored and used in conjunction with the standard specification components in the tolerance calculator. A basic version does not need to support the use of custom calculators. The Tolerance Calculator page contains the interface features in Table 27.

FIG. 33 is a representation of what the Automatic Line Generator page looks like. The Automatic Line Generator page is displayed when the tolerance calculator's Calculate button is clicked. When the new row is inserted, the user will be prompted to enter additional information to be placed in the new data sheet row. The Automatic Line Generator page contains the interface features in Table 28.

The tolerance calculator embeds the equipment specification data, used to calculate tolerances, into data sheet rows. A composite value for the standards requirement (0.25*Tolerance) is also embedded. This information is displayed for each data sheet row.

The Nominal Value and Tolerance columns of a data sheet play major roles in the Calibration Process Manager's overall function. The columns contain data that is used to assess in tolerance status during data collection and to interface with Specification Tracking instrument specifications. If the user were to directly edit the contents of these critical fields, the system could no longer be assured of their data integrity. It is therefore necessary to provide a means of modifying the content of the fields while preserving numerically critical content. A special editor page is provided for each of these fields to make this possible. These editors should be used to modify these fields. If a user directly edits the fields, all UUT specification and Specification Tracking Instrument references are dropped and the data sheet row looses all of its intelligence.

FIG. 34 is a representation of what the Nominal Value Wizard page looks like. The Nominal Value Wizard allows the user to configure the Nominal Value field of a data sheet row. All formatting is handled by the wizard. The user can edit the trailing text field without invalidating the field's data integrity, but any changes to field parametric values will invalidate any Specification Tracking Instrument range references. Changing the first parameter will invalidate all specification data for the data sheet row. Calibration Process Manger uses the first parameter of the nominal value field as its reference for the nominal value of calibration data collected. If data integrity is compromised, you must recalculate tolerances using the integrated tolerance calculator and reassign Specification Tracking instrument ranges. The Nominal Value Wizard page contains the interface features in Table 29.

FIG. 35 is a representation of what the Tolerance Column Wizard page looks like. The Tolerance Column Wizard allows the user to configure the Tolerance field of a data sheet row. All formatting is handled by the wizard. The user can edit the TAR, EMU, remark flag, and trailing text field without invalidating the field's data integrity. Calibration Process Manger uses the Tolerance field content to assess the in tolerance condition of calibration data collected. If data integrity is compromised, you must recalculate tolerances using the integrated tolerance calculator. The Tolerance Column Wizard page contains the interface features in Table 30.

FIG. 36 is a representation of what the Unit of Measure by Symbol page looks like, The Unit of Measure by Symbol page allows the user to search for a desired unit of measure by its symbol. The form is activated by clicking on the main form's Units button when the main form is in the Data Sheet Designer mode and the Lock Status' Edit option is selected. The Unit of Measure by Symbol page contains the interface features in Table 31.

The Test Point Generation Wizard allows the user to predefine test point values, tolerance format, functions tested descriptions, and boilerplate information. The wizard can contain multiple test point definitions. The tolerance calculator will automatically be configured when the test point definition is selected, and setup an array of test points.

FIG. 37 is a representation of what the Wizard Loader page looks like. The Wizard Loader allows the user to load preset wizards for use in creating data sheets. This page is accessed through the Tools, Wizards, Test Point Wizards, Load menu option. The Wizard Loader page contains the interface features in Table 32.

FIG. 38 is a representation of what the Wizard Workshop page looks like. The Wizard Workshop allows the user to create test point wizards for use in creating data sheets. This page is accessed through the tools, wizards, test point generators, load menu item. The Wizard Loader page contains the interface features in Table 33.

The Data Sheet Generation Wizard allows the user to generate a complete data sheet by entering data into a module specifically designed for a specific instrument type. Data sheet wizards posses an advanced of knowledge of the rules applicable to the instruments for which they are designed. Once data sheets are created with the module, they can be edited and manipulated in the same manner as any other data sheet.

FIG. 39 is a representation of what the Pressure Gauge Data Sheet Generator page looks like. This is a Data Sheet generation wizard that will prompt the user for specific data relating to pressure instruments. Once the data has been inputted the entire data sheet is generated. This page is accessed by using the Tools, Data sheet Generators, Pressure option in the menu bar. The module supports the creation of multiple data sets within a single data sheet, i.e., Multiple sensor modules used with a single reader. Numeric fields on this page will turn red if an improper entry is made and an error message is then displayed.

The Pressure Gauge Data Sheet Generator uses specific information, embedded in the Suite's master units of measure table, to identify “absolute” and “gauge” pressure units of measure. The group names for these units must be “Pressure (absolute)” and “Pressure (gauge)”. These two groups contain the units that can be directly cross referenced to each other. Changing the group names or adding units that don't cross reference may cause errors in the Pressure Gauge Data Sheet Generator module. The Pressure Gauge Data Sheet Generator page contains the interface features in Table 34.

FIG. 40 is a representation of what the Test Point Uncertainty Wizard page looks like. The Test Point Uncertainty Wizard page is accessed from the Process Manger's main page when the main page is in the Data Sheet Designer mode. Click on the Measurement Uncertainty button (this is the button with the Σ symbol). The Test Point Uncertainty Wizard is used to view and edit the currently selected test point's measurement uncertainty model. The Calibration Process Manager will automatically manage the measurement uncertainty model when one or more Specification Tracking instrument ranges are assigned to the test point. The user can modify this model if the user has the necessary permissions. A fixed uncertainty value can also entered into the Tolerance Column Wizard page. If a value is entered directly into the Tolerance Column Wizard page, that value will override the uncertainty model.

The user can enter both type A and type B uncertainties. Some of the values used by the measurement uncertainty model can be set in the System Configuration page's “Measurement Uncty” configuration options. The measurement uncertainty model is also used in the calculation of the test accuracy ratio when directed to do so in the System Configuration page's “Measurement Uncty” configuration options.

The uncertainty model, test accuracy ratio, and applicable displayed results are always relevant to the currently selected Specification Tracking Interface mode. When in the Standards used mode, the Model is using the actual calibration standards' specifications, when in the Default Standards mode, the model is using the default standards' specifications, etc. The values displayed will vary as the Specification Tracking Interface mode is changed. Pay close attention to the Specification Tracking Interface mode indicators in the data sheet's Nominal Value column. The Test Point Uncertainty Wizard page contains the interface features in Table 35.

FIG. 41 is a representation of what the Uncertainty Element Editor Page looks like. The Uncertainty Element Editor Page allows the user to edit parameters of an uncertainty element.

The Uncertainty Element Editor Page contains the interface features in Table 36.

Specification Tracking

The Specification Tracking system records and manages instrument specifications. Specification Tracking was primarily designed for use with the Calibration Process Manager. The Calibration Process Manager has a built in interface to use the specification data stored within the Specification Tracking database system.

Specification Tracking defines instruments using three hierarchical categories: Instruments, Functions and Ranges. The instrument is subdivided into instrument functions, which are subdivided into instrument ranges. Once an instrument is assigned to a data sheet, its ranges can then be assigned to individual data sheet rows. Calibration Process Manager has tools to automate the range selection process.

Specification Tracking Instruments make use of the underlying system of serialization in the CPMS that provides unique serial numbers to both the instrument and individual instrument ranges. As explained below, each instrument and range is assigned two serial numbers: A Permanent Unique Identifier (PUI) and a Dynamically Unique Identifier (DUI). The PUI is assigned when an object is created or altered in a manner that would make it unlinkable to its past usage. The DUI is assigned any time the object is modified/saved. These unique identifiers allow the Calibration Process Manager to track and relate linkages of these objects for historical and statistical purposes. Once assigned to a data sheet, these serial numbers form a permanent link between the data sheet/Calibration and the instrument's applicable ranges.

When instrument ranges are assigned to data sheet rows the Calibration Process Manager can use the data to determine Test Accuracy Ratios, Estimated Measurement Uncertainties, Instrument range utilization, and assist in the failure analysis of calibration standards.

The interface has three modes that correspond to each of the three instrument specification data applications used within the Calibration Process Manager. The Specification Tracking Interface mode indicators allow the user to determine which mode of the Specification Tracking Interface is active, even when the Specification Tracking Instruments Interface is not visible.

The Calibration Process Manager's test point measurement uncertainty model, test accuracy ratio, and applicable displayed results are always relevant to the currently selected Specification Tracking Interface mode. i.e.: When in the Standards used mode, the Model is using the actual calibration standards' specifications, when in the Default Standards mode, the model is using the default standards' specifications, etc. The values displayed will vary as the Specification Tracking Interface mode is changed. The following table describes the three modal applications of specification data. In the “Myself” mode the Specification Tracking instrument ranges of the instrument to be calibrated are assigned to applicable data sheet rows. This self definition information is used when the instrument to be calibrated is, itself, used as a calibration standard. When a calibration record is loaded into the Calibration Process Manger, the Statistics mode can be used to generate an Instrument Range Utilization Report. The report is generated for the currently selected data sheet row's applicable Specification Tracking instrument range. The report shows the instrument ranges' use in other calibrations. This report is extremely useful in performing calibration standard failure analysis.

The “Def Stds” mode allows the data sheet designer to assign calibration standard instruments to the data sheet and assign instrument ranges to data sheet rows. These assignments represent the default standards, with range assignments, recommended for use when actual calibrations are performed. If default standards are assigned, the user has only to click on the “Stds Used” pages' “Use ‘Default’ stds” button to transfer these predetermined selections to “Stds Used”. The data derived through these assignments will also permit the Calibration Process Manager to estimate accuracies, accuracy ratio's and estimated measurement uncertainties to assist the data sheet designer in determining the adequacy of test conditions.

The “Stds Used” mode is designed to assign calibration standard instruments to the data sheet and assign instrument ranges to data sheet rows at the time of calibration. The user will also assign the specific instrument asset numbers for the standards used. The data derived through these assignments will permit the Calibration Process Manager to calculate, record, and report test accuracy ratio's and estimated measurement uncertainties for data sheet test points. The modes are in table 37.

The Specification Tracking Instruments Interface opens in the lower portion of the screen. The data sheet grid is reduced in height by approximately a third, in order to accommodate the Specification Tracking Instruments Interface. The Specification Tracking Instruments Interface can be opened by selecting the View, Show Specification Tracking Instruments menu option.

FIG. 42 is a representation of what the Calibration Process Manger's main page (Data Sheet Designer mode) looks like with the Specification Tracking Instruments Interface displayed.

FIG. 43 is a representation of what the Specification Tracking Instruments Interface (Myself mode) looks like. In the Myself mode, specifications of the instrument being calibrated are assigned to the instrument itself. This self definition information is used to associate an instrument's calibration test points with its Specification Tracking instrument ranges. The process synchronizes Specification Tracking instrument and range serial numbers with the data sheet that calibrates the instrument. This identification process allows the Calibration Process Manger to link the usage of an instrument range to the data sheet on which it is calibrated.

This self awareness is especially important when the instrument is a calibration standard. When a calibration record is loaded into the Calibration Process Manger, the Statistics mode can be used to generate an Instrument Range Utilization Report. The report is generated for the currently selected data sheet row's applicable Specification Tracking instrument range. The report shows the instrument ranges' use in other calibrations. This report is extremely useful in performing calibration standard failure analysis.

Another reason to perform this assignment is to compare data sheet specifications with Specification Tracking specifications. When performing an auto-assignment of instrument ranges to the data sheet, Calibration Process Manager will not auto assign an instrument range to a data sheet row if the calculated accuracies do not agree within 0.1% of each other. If the Calibration Process Manager is unable to make a range assignment, either the data sheet or instrument's specifications are in error.

The Specification Tracking Instruments Interface (Myself mode) contains the interface features in Table 38.

FIG. 44 is a representation of what the Specification Tracking Instruments Interface (Default Standards mode) looks like. In the Default Standards mode, specifications of the standards, planned for use during the execution of the data sheet (calibration), are assigned to the data sheet. This assignment of Specification Tracking instruments and instrument ranges to a data sheet's test points will enable the data sheet designer to pre-define a desired test point instrumentation configuration. When a user performs an actual calibration, with the data sheet, the user can select the Standards Used mode's “Use ‘Default’ Stds” button to copy the pre-defined configuration to the Standards Used configuration. The only other thing the user will have to do is assign asset numbers to the actual standards used. Another important purpose for assigning default standards is to provide the Calibration process Manger with the information necessary to calculate standards accuracies, test accuracy ratios, and estimated measurement uncertainty. This information is very useful in the calibration design process. The Specification Tracking Instruments Interface (Default Standards mode) contains the interface features in Table 39.

FIG. 45 is a representation of what the Specification Tracking Instruments Interface (Standards Used mode) looks like. In the Standards Used mode, specifications of the standards used during calibration are assigned. When a user performs a calibration, the user can click the “Use ‘Default’ Stds” button to copy the pre-defined default standards configuration to the Standards Used configuration. The only other thing the user will have to do is assign asset numbers to the actual standards used. If no default configuration is available or another configuration is used, the User can configure the standards at the time of calibration.

By associating the standards and standard ranges used during the calibration, to the data sheet test points, standard range utilization reporting can be achieved and greatly reduce the work required to perform standards failure analysis. The standard range data is also critical to the Calibration Process Manager's ability to calculate standards accuracies, test accuracy ratios and build an uncertainty model to calculate estimated measurement uncertainties. The Specification Tracking Instruments Interface (Standards Used mode) contains the interface features in Table 40.

FIG. 46 is a representation of what the Specification Tracking Interface mode indicators look like. The Specification Tracking Interface mode indicators allow the user to determine which mode of the Specification Tracking Interface is active, even when the Specification Tracking Instruments Interface is not visible. Each cell of the data sheet's Nominal Value column will have three small boxes located at the top of the cell. The indicators are only present in actual test point rows of the data sheet. The indicators appear in the same order as the mode selection buttons in the Specification Tracking Instruments Interface. A carrot symbol (▴) under one of the indicators indicates the present mode. The presence and color of the symbols convey meaning to the status of instrument ranges assigned, or not assigned, to the test point. The Specification Tracking Interface mode indicators convey the information in Table 41.

FIG. 47 is a representation of what the Instrument Specifications Catalog page looks like.

The Instrument Specifications Catalog page allows the user to choose an instrument to add to a data sheet. The Instrument Specifications Catalog page is accessed from the Calibration Process Manager's main page's Specification Tracking Instruments Interface by clicking on the Add button while in any of the three Specification Tracking Interface modes. The Instrument Specifications Catalog page contains the interface features in Table 42.

FIG. 48 is a representation of what the Auto Assign Instrument Ranges page looks like. The Auto Assign Instrument Ranges page is displayed when the user clicks the Auto Assign button, located on the Specification Tracking Instruments Interface's instrument section, while in any of the three Specification Tracking Interface modes. The Auto Assign Instrument Ranges page is displayed to inquire if the assignment is for the instrument currently selected in the Specification Tracking Instruments Interface's Instrument List grid or if the assignment is for all instruments assigned to the data sheet. The page also displays the following warning to the user describing the limitations of automatic instrument range selection: “Warning: This function will replace all previous assignments with the standard(s) most accurate range. After this operation, you should review my choices. After all, I am just a machine.”

Although auto selection is capable of choosing an inappropriate range, based on parametric matching and best accuracy, it is usually a good idea to let the Calibration Process Manager have a try at auto selecting the ranges. It is usually easier to change the few inappropriate selections than it is to do them all manually. Of course, the user's experience with the system and knowledge of the parametric matching probability of the instruments in question, is the best determination of the time saved by auto matching. This page contains the interface features in Table 43.

FIG. 49 is a representation of what the Manual Instrument Range Selector page looks like.

When the Calibration Process Manager is unable to auto select an instrument range or selects an inappropriate instrument range for a test point, the user must intervene. This intervention is performed using the Manual Instrument Range Selector. The Manual Instrument Range Selector page is accessed from the Calibration Process Manager's main page's Specification Tracking Instruments Interface by clicking on the Manual Assign to TP button while in any of the three Specification Tracking Interface modes. This page contains the interface features in Table 44.

FIG. 50 is a representation of what the Instrument Substitution page looks like. The Instrument Substitution page is displayed when clicking the “Replace selected with” button on the Calibration Process Manager's main page's Specification Tracking Instruments Interface. This button is available while in any of the three Specification Tracking Interface modes.

The Instrument Substitution page is used to remove the currently selected instrument's range assignments from all data sheet test point rows and replace those assignments with ranges from the instrument selected on the Instrument Substitution page. The Calibration Process manger will attempt to make range assignments for the newly selected instrument. Assignments will only be made for test point rows that had a range assigned for the instrument being replaced. All range assignments for the instrument being replaced will be removed, even if the newly selected instrument does not have an applicable range to assign in its place. This behavior is designed to reduce confusion as to why the removed instrument might still have ranges assigned to the data sheet.

The Instrument Substitution page also displays the following warning: “Warning: You should review all test points after this operation to ensure my selections are appropriate to the test point application. After all I will select ranges that meet my requirements, but the question is do they meet yours?” This page contains the interface features in Table 45.

FIG. 51 is a representation of what the Set Instrument Asset ID's page looks like. Asset ID's should be assigned to each standard used while performing a calibration. This option is only available when in the Specification Tracking Interface Standards Used mode (applicable only during an actual calibration). The Set Instrument Asset ID's page is accessed from the Calibration Process Manager's main page's Specification Tracking Instruments Interface by clicking on the Asset IDs button while in the Specification Tracking Interface “Stds Used” mode. This page contains the interface features in Table 46.

Calibration Process Manager is designed to automate data sheets for the calibration of measuring and test equipment. Once designed, Calibration Process Manager data sheets can then be used to collect and store calibration data for up to eight instruments simultaneously. Automation scripting can be added to these data sheets to configure instruments, capture data, perform mathematical operations, and create instrument test points dynamically.

The scripted data sheet may result in a completely unattended calibration, a series of user prompts and calculations, or only one row of a data sheet may have automation scripting. This flexibility is designed to maximize calibration productivity while minimizing the data sheet design process.

Whatever your choices in script design, the starting point is always a data sheet. The data sheet can be edited before, during, and after the automation scripting process.

The Calibration Process Manager will allow the user to add and configure scripting commands to any row of a data sheet. The system will allow the operator to cut and paste individual script commands, a series of script commands, or entire data sheet rows. Each row of a data sheet is an independent island of automation scripting. These islands can be bridged together by navigation script commands that produce a continuous execution of all or a portion of a data sheet.

Any data sheet can have scripting commands. The automation scripting editor manages the relationship of automation commands to data sheet rows.

The Calibration Process Manager's automation scripting system is based on the grouped and sequenced execution of parameterized script commands. Appendix C describes each of the commands available and their parameters. Note: Most command parameters allow the use of a user defined variable in place of a hard coded (fixed) value.

With the Master Mode is set to Data Collection, the View, Show Script menu option displays the command list box in the lower right corner of the screen. The data sheet grid is reduced in width by approximately half, in order to accommodate the command list box. The command list box contains the interface features in Table 47.

FIG. 52 is a representation of what the Automation Command Editor page looks like. This page allows the user to select and configure commands to be used in an automation script. This page also allows the user to assign the command to a command group to facilitate sequential execution of a collection of commands. As script commands represent the principle usage of user defined variables, this page is where the data sheet's user defined variables are managed. This page contains the interface features in Table 48.

FIG. 53 is a representation of what the Data Sheet Variables page looks like. The data sheet variables page allows the user to see the present content of all data sheet variables. The Automation scripting system uses these variables in many ways such as: Command parameter values, in equations, to hold user query values, etc. Any command parameter may have a user defined variable used in place of a direct value.

FIG. 54 is a representation of what the Data Sheet Variable Editor page looks like. The data sheet variable editor page allows the user to create and edit data sheet variables. This page contains the interface features in Table 49.

FIG. 55 is a representation of what the Command Group Editor page looks like. The Command Group Editor page is where the user can create command groups. Only one each, of command groups may be added into the list. Calibration Process Manager will display a warning screen if the user attempts to add a second iteration of a command group. Command groups are used to bind a set of commands into a command sequence. There are two types of command groups.

Interface Groups. These groups can be defined by the script author. When the user invokes the command menu, a unique list of all interface groups in the script, for the selected data sheet row, will appear on the menu. The Script author may assign a numeric “Key” value in the range of 0-9 to each interface group. The “Key” value will be displayed to the left of each item on the command menu. When the user presses the corresponding key, all of the commands assigned to the selected group are executed sequentially. Interface groups are displayed with a black font in the scripting system when created by the script author.

System Groups. These groups may not be edited by user or have “Key” values assigned to them. Their purpose is to bind script commands together for special behaviors that are programmed into the Calibration Process Manger's scripting system.

System and Interface groups may both be used within the same data sheet row to achieve a desired effect. While some script commands are designed to operate without being assigned to a command group, most commands will not execute unless they have a command group assigned to them.

This Command Group Editor page contains the interface features in Table 50.

Globally Unique Identifiers

Implementation of the Calibration Process Manager is facilitated by a data structure for recording calibration data from a UUT. Typically, with reference to FIG. 80, this data structure will be stored on a hard drive memory 54 of the computer 52 which is connected to the calibration testing unit 56, and the UUT 58. It is possible to have multiple UUTs 58 connected and tested using the present invention.

As will be known in the art with reference to this disclosure, it would be possible to store a data structure of the present invention on any computer readable medium, such as floppy drives, dismountable hard drives, DVDs, CD-ROM, CD-R, CD-RW, memory cards, and the like.

The structure centers on use of two guaranteed identification address globally unique identifiers (“GUID”). The generation of GUIDs is known in the art, and information relating to GUIDs may be found in the Microsoft Knowledge Base article Q176790 “HOWTO: Use CoCreateGUID API to Generate a GUID with VB.”

The first GUID used in the present invention is a permanent unique ID, or “PUI.” The second GUID used in the present invention is a dynamic unique ID, or “DUI.”

This underlying system of serialization provides the unique identifiers to both the data sheet and individual rows of the data sheet. Preferably, serial numbers are used as the identifiers. Each data sheet and data sheet row is assigned two serial numbers: A Permanent Unique Identifier (PUI) and a Dynamically Unique Identifier (DUI). The PUI is assigned when an object is created or altered in a manner that would make it unable to link to its past usage. A new DUI is assigned each time the object is modified/saved.

These unique identifiers allow the Calibration Process Manager to track and relate linkages of these objects for historical and statistical purposes. The relationship of the unique identifiers to data sheet and calibration history should be understood and considered any time a datasheet is modified. Calibration test point history is related to data sheet row by its PUI. Changing parametric data in the Nominal Value cell of a data sheet row will cause the Calibration Process Manger to issue the row a new PUI. When these parameters are changed the Calibration Process Manager must assume that the quantitative relationship to calibration history for the test point is no longer applicable. The result is that the data sheet row is no longer directly linkable to calibration test points that used the row in the past. The security of data preservation is not broken, but statistical analysis will be disrupted. The bottom line is that the user must consider these impacts in the decision to alter the data sheet.

The system permits a secure environment along with an audit trail to track changes to the system parameters. Archiving of records is also possible.

Using the PUI and DUI identifiers, for example, it will be possible to locate all UUTs that were measured with a particular calibration testing unit 56. If it is later determined that the particular calibration testing unit 56 is itself out of calibration in a particular range, the PUI/DUI identifiers permit identifying each UUT 58, and each range tested, that may be affected by the our of calibration testing unit.

Method for Calibration

With reference to FIG. 81, method 200 for calibrating a UUT for a specific calibration function is described, comprising the steps of receiving 202 a first identification attribute associated with a UUT; receiving 204 a second identification attribute associated with a reference measuring unit; receiving 206 a specific calibration function to be tested; maintaining 216 in a first memory a reference database of one or more than one second identification attribute in holding relationship to one or more than one reference identification address, each reference identification address being associated with a single calibration function; looking up 208 in the reference database, the reference identification address being held by the second identification attribute, and associated with the specific calibration function; selecting 210 a unique record identification address; receiving 212 a value as found for the specific calibration function for the UUT; storing 214 in a second memory the value as found in a being-held relationship to the record identification address; and storing 216 in a third memory the record identification address in a being-held relationship to the reference identification address.

In one preferred embodiment, either the first identification attribute (not numbered) or the second identification attribute 122, or both the first identification attribute and the second identification attribute 122, can be an asset number.

In a further embodiment, steps may be added of receiving (not shown) a value as left for the specific calibration function for the UUT and storing in the second memory the value as left in a being-held relationship to the record identification address. Additionally, optionally steps (not shown) may be added returning a test accuracy ratio, or returning an estimated measurement uncertainty, or automatically converting the units of the received value as found.

In a further embodiment, method 200 may further comprise maintaining in a fourth memory an equipment database correlating for individual make and model of equipment, a nominal value to calibration function; receiving make and model of equipment attributes for the UUT; looking up in the equipment database, the nominal value for the specific calibration function for the received make and model of equipment; returning the nominal value; and calculating a calibration tolerance and returning the limits. In a still further embodiment, additional steps may be receiving a value as left for the specific calibration function for the UUT and storing in a fifth memory the value as left in a being-held relationship to the record identification address. The method may still further comprise the step of indicating whether the value as found or the value as left is within the limits of the calibration tolerance.

Management System

As shown in FIG. 82, a Calibration Process Management Program 10 implementing method 200 is shown, of which the previously described Calibration Process Manager is one embodiment, comprising a set of modules including calibration tools 12, engineering tools 14, and management tools 16. Multiple formerly independent modules can thus be integrated into a Calibration Process Management System (“CPMS”) 50 comprising program 10, residing on memory 54 of an appropriate computer 52, and an optional printer 60. A data sheet 62 may then be printed. A sample of a data sheet 62 is shown in FIG. 83.

The calibration tools module 12 comprises calibration tools 121, and optionally data sheet generation wizards 122, and editors and calculators 123. The engineering tools module 14 comprises measurement analysis tools 143 and optionally failure analysis tools 141, drift analysis tools 142, uncertainty tools 144, and interval analysis tools 145. The management tools module 16 comprises datasheet management tools 161, and optionally security access 162, and workload distribution 163. These have been described in various embodiments in the Calibration Process Manager above. Other embodiments of these tools will be evident to those skilled in the art with reference to this disclosure.

It would be possible to implement the CPMS on any type of personal computer, such as a Pentium® class machine. Operating systems useable include those available from Microsoft®, including Windows® 98, ME, 2000, and XP. The computer memory can be any media useable for storage of computer data, including but not limited to hard drives, floppy drives, removable drives, RAM, ROM, DVDs, and CD-R.

It is possible to implement management program 10 as a 32 bit, Windows 9x, NT, or 2000 based program, designed for standalone or Client/Server SQL database applications. In one embodiment, it can be designed and developed to satisfy ISO-17025, ANSI Z-540, 10 CFR 50 Appendix B, ISO-9002, GMP, and other stringent quality requirements for calibration data collection.

Certain aspects of Calibration Process Management Program 10 are desirable, and will now be described. It will be understood that individually each of these are optional.

An integrated tolerance calculator allows a data sheet designer to generate test point row data by merely entering nominal test point values and equipment specification data. The tolerance is calculated, formatted, and then the new test points are inserted into the data sheet. Preferably, the calculator uses a smart rounding system to appropriately round tolerance values, and supports both standard specifications (% of I.V., ppm of I.V., % of F.S., ppm of F.S., ±n Units of measure, and ±db) and custom specifications. Custom specifications are more complex specification components such as: “±0.025% of I.V. per volt above 750 volts”. Custom specifications can be defined by the user, then used in combination with the standard specification components in the tolerance calculator.

A custom tolerance calculator is used to calculate tolerances, based on specification components that are more complex than the standard specification components (% of I.V., ppm of I.V., % of F.S., ppm of F.S.±n Units of measure, and ±db). These more complex specification components are things such as: “±0.025% of I.V. per volt above 750 volts”. CPMS 50 provides a special set of tools that allow you create your own library of custom specification statements and then use them in combination with the standard specification components in tolerance calculator.

An equation system permits equations to be constructed using a user-friendly equation editor. The system uses, standard operands, a function library, user defined variables, and conditional clauses in equations. The equation system can be used throughout CPMS 50 to create and execute equations in such operations as: custom calculators, units conversion, automation scripting math commands, etc.

When creating data sheets, development productivity and format continuity are important factors. This is where data sheet generation wizards fit the bill. These wizards allow for the predefinition of test point values, tolerance format, function tested descriptions, and data sheet boilerplate information. A single data sheet wizard can contain multiple test point definitions.

As an example, a wizard for digital multimeters with a range base of 200 (i.e. 200 mV Range) might contain the following test point definitions shown in Table 64.

Selecting one of these test point definitions will automatically configure the tolerance calculator with predefined numeric and tolerance formats, and setup an array of test points. When the new test points are inserted into the data sheet, the Step Number and Function Tested descriptions are taken from the wizard test point definition. Any of the predefined values can be overridden, if necessary.

Data sheets can be created using special data sheet wizards. These wizards prompt the user for specification data then generate an entire datasheet. An example of a user interface suitable for use in a data sheet generation wizard is shown in FIG. 21.

Multiple Channel Data Collection. For many types of instruments, it is much more efficient to collect data for more than one instrument at the same time. CPMS 50 allows you to do this, providing the instruments use the same data sheet. Up to eight simultaneous sets of measurement data can be collected within CPMS 50 in one embodiment. Each set of measurement data is referred to as a “Channel”. Each channel has a display module for “As Found”, “As Left”, and “Out of Tolerance” data. All eight channels can be displayed and edited simultaneously.

Automatic “Out of Tolerance” detection. When a measured value is recorded for an instrument channel, CPMS 50 will compare the value to the instrument's “Tolerance”, indicate the “Out of Tolerance” status, and display the percentage of the tolerance consumed.

Data collection via automation scripting. Instrument data can also be collected through the use of an automation scripting system. This allows data collection from GPIB, or RS-232, custom user prompts, or the result of scripted mathematical operations.

Storage and retrieval of collected data. Measurement data collected for each channel can be stored independently. This data can be recalled or reprinted at any time. The data can be either recalled, into any one of the eight instrument channels, or opened as an independent data sheet.

Automation Scripting. CPMS 50 allows you to add automation scripting commands to any row of a data sheet. Scripting data sheet rows independently has many advantages, but chief among them is the direct interaction between a row's script commands, test point data, and measurement data. With this direct correlation you can apply automation commands to a specific row or section of a data sheet, by simply selecting the applicable data sheet row. If only one section of a data sheet is to be automated, no action is required in any unaffected row. Even when scripting is available for a section/row of a data sheet, it can also be treated as just that, a simple data sheet row. The user can simply enter the measurement data or run the applicable part of the script.

Editing the automation script for a data sheet is simple. Script commands for a data sheet row are displayed whenever that row has focus in the data sheet editor. The script editor makes it simple to cut and paste a series of commands, from one data sheet row, to another data sheet row, or even another data sheet. When copying and pasting entire data sheet rows, the data sheet editor will also copy and paste all applicable commands.

Scripting of preexisting data sheets. Any data sheet can have scripting commands added to it. The result is incremental development. Whenever someone creates a data sheet, they are laying out the framework for an automation process. When scripting is undertaken, this work does not have to be repeated. As a result of the direct relationship of the script to the data sheet row, evaluation of measured values to the calibration tolerances is internally handled, with no scripting required.

Scripting commands are available for both GPIB and RS-232 operations.

CPMS 50 has the ability to use scripting commands to actually build a data sheet. Scripting commands are available to prompt the user for specification data, manipulate the tolerance calculator, perform math operations, and generate test points. This type of scripting is very useful as replacement for generic data sheets. Creating self generating data sheets for instruments such as torque wrenches, pressure gauges, micrometers, etc., is very easy.

The automation scripting system features commands can make full use of a CPMS 50 equation system described above. Interaction with external applications can be done by including in the scripting commands Object Linking and Embedding (OLE) commands. These commands allow the scripting system to share data with external applications, i.e., MATHCAD, WORD, EXCEL, etc. Calibration instructions can be created with a Rich Text Format (RTF) instruction editor or imported from another word processor. The instructions can be displayed using a script command.

Groups of commands can be saved to a file. These files are intended to serve as a command group library. Groups of commands can be inserted directly into a script from one of these files. Groups of commands can also be cut and pasted across rows or even data sheets.

An intelligent SI Units of Measure converter automatically interprets measurement units for the nominal values in the calibration data sheet. The Units of measure engine also automatically converts measurement units be the UT and applied standards. The Units of measure engine can also be used as a stand alone units converter for quick conversions.

Specification Tracking

Specification Tracking is an optional CPMS 50 module that contains a library of calibration standards accuracy specifications and/or uncertainties. Specification Tracking enables CPMS 50 to assign calibration standards, and their related function, range and accuracy specifications to data sheets and applicable UUT calibration data. Standards accuracy specifications are entered through a unique user interface which provides a systematic, logical architecture for building specification data.

Standards specifications can be divided by Function, Parameter, Range, Accuracy, Resolution, and other metrological criteria to properly identify the specification. Specification data stored in Specification Tracking can be used throughout CPMS 50 in the calculation of Estimated Measurement Uncertainty (EMU), Test Accuracy Ratios (TAR) and failure analysis.

CPMS 50 can be used in the field to collect calibration data and merge data into the main system by adding optional Mobile PC support.

The CPMS can also optionally automatically calculate each test point's estimated measurement uncertainty (“EMU”), using principle sources of error from standards accuracy specifications, inverse normal distribution function, in-tolerance probability, and uncertainty contributed by the measurement system resolution. These sources of error are combined with a suitable coverage factor and expressed as EMU. This meets the Quality Standards and Practices requirement of ISO/IEC 170255.4.6 “Estimation of uncertainty of measurement” which states in section 5.4.6.2 “[t]esting laboratories shall have and apply procedures for estimating uncertainty of measurement. In certain cases the nature of the test method may preclude rigorous, meteorologically and statistically valid, calculation of uncertainty of measurement. In these cases the laboratory shall at least attempt to identify all the components of uncertainty and make a reasonable estimation.” ISO/IEC 17025, “General Requirements for the Competence of Testing and Calibration Laboratories.”

There are two distinct testing methods; Type A tolerance testing (method of evaluation of uncertainty by the statistical analysis of series of observations) and Type B uncertainty testing (method of evaluation of uncertainty by means other than the statistical analysis of series of observations). In tolerance testing measurement reliability is the objective, parametric data is not utilized, and is typically done in a secondary calibration laboratory. In uncertainty testing, typically done in a primary standards laboratory, measurement uncertainty is the objective, and parametric data is utilized.

Preferably, the CPMS is capable of Type B evaluation of uncertainty. It is sufficient to assume that a heuristic estimate is adequate, and that standards and UUT are the principle sources of error, where the standards contribution is based on in-tolerance probability, and the UUT contribution is based on measurement system resolution.

One way of defining the uncertainty contributed by the standard is shown in Equation (Eq. 1), where L_(s) is the standard accuracy specification, Φ⁻¹ is the inverse normal distribution function, and P is the in tolerance probability.

$\begin{matrix} {u_{s} = \frac{L_{s}}{\Phi^{- 1}\left( \frac{1 + P}{2} \right)}} & \left( {{Eq}.\mspace{14mu} 1} \right) \end{matrix}$

One way of defining the uncertainty contributed by the UUT is shown in Equation (Eq. 3), where X._(R) is the measurement system resolution (e.g., ½LSD)

$\begin{matrix} {u_{R} = \frac{x_{R}}{\sqrt{3}}} & \left( {{Eq}.\mspace{14mu} 2} \right) \\ {u_{R} = \frac{X_{R}}{\sqrt{3}}} & \left( {{Eq}.\mspace{14mu} 3} \right) \end{matrix}$

The combined standard and UUT uncertainty is then given by Equation (Eq. 4), where u_(S) is the standard uncertainty and u_(R) is the UUT uncertainty.

u _(C)=√{square root over (u _(S) ² +u _(R) ²)}  (Eq. 4)

The estimated measurement uncertainty may then be expressed by Equation (Eq. 5), where k is a coverage factor (e.g. k=2). “Estimates of uncertainty are derived form the statistical concept of the standard deviation. The standard deviation is a characteristic or number that describes the amount of variability of a distribution of measurements.” Jackson, D. and Castrup, H., “Uncertainty Propagation in Calibration Support.”

U=k·u _(C)  (Eq. 5)

Substituting Equation (Eq. 4) into Equation (Eq. 5), we can obtain an approximate value for U_(echelon I) in a Type B evaluation using Standard and UUT data from Equation (Eq. 6), where k_(factor) is the coverage factor.

U _(echelon I) ≈k _(factor) ·[u _(standard) ² +u _(resolution) ²]^(0.5)  (Eq. 6)

Similarly, we can obtain an approximate value for U_(echelon II) in a Type A evaluation using parametric test data with Equation (Eq. 7).

U _(echelon II) =k(υ_(eff) ,p)[Σ(c _(i) u _(standard) _(i) )²+Σ(c _(j) u _(other) _(j) )² +u _(test data) ²]^(0.5)  (Eq 7)

Further, we can obtain an approximate value for U_(echelon III) in a Type A evaluation using parametric historical data with Equation (Eq. 8).

U _(echelon III) =k(υ,p)[Σ(c _(i) u _(standard) _(i) )²+Σ(c _(j) u _(other) _(j) )² +u _(historical data) ²]^(0.5)  (Eq. 8)

A CPMS preferably automatically calculates each test point's test accuracy (“TAR”) ratio between the UUT and the applicable standard's function and range, preferably in accord with ANSI/NCSL Z540-1-1994 “Calibration Laboratories and Measuring and Test” section 10.2 b): “The laboratory shall ensure that the calibration uncertainties are sufficiently small so that the adequacy of the measurement is not affected . . . the collective uncertainty of the measurement standards shall not exceed 25% of the acceptable tolerance (e.g., manufacture's specification) for each characteristic of the measuring and test equipment being calibrated or verified.”

In one preferred embodiment, the CPMS uses an algorithm that combines the calibration tolerance of the UUT, and the collective uncertainty of the standard to derive the Test Accuracy Ratio or TAR. This method represents the model specified in ANSI/NCSL Z540-1-1994. Section 10.2, and is expressed in Equation (Eq. 9), where TAR is the Test Accuracy Ratio, Lx is the calibration tolerance of the UUT, and the radical denominator term is the collective uncertainty of standards, k=1.

$\begin{matrix} {{T\; A\; R} = \frac{L_{X}/\sqrt{3}}{\sqrt{\sum u_{S}^{2}}}} & \left( {{Eq}.\mspace{14mu} 9} \right) \end{matrix}$

Failure Analysis. This feature enables the user to automatically evaluate out-of-tolerance conditions by tracking the function, range and test point information between each standard and the unit under test. Failure analysis pertains to compliance with ISO 17025 paragraph 4.9 b) or Z540-1 paragraph 8.2. That is, the laboratory shall examine the effect of non-conforming work or equipment defects (out-of-tolerance conditions) on other work. Most labs keep track of what standards are used to calibrate what equipment. Therefore, the starting point for failure analysis is an out-of-tolerance condition on a standard and a list of items on which the standard was used. It is then up to the evaluator to re-trace each calibration to determine whether or not the individual range and test point that failed on the standard was actually used on the UUT, to quantitatively assess what effect the failure had, and to notify the client if the effect was significant. Imagine doing this if the standard is a multifunction meter calibrator and the UUT list contains 100 items, and across the laboratory's inventory of standards.

The CPMS enables this evaluation to be done automatically by keeping track of the function, range and test point information between each standard and UUT. By knowing the applicable specifications and the magnitude of the failure, it could determine whether or not the failure had an adverse effect on the calibration. It could produce a list of items that were actually affected, where and by how much. It could even prepare this information for transmittal to the client. This a huge feature because most labs are overwhelmed by this or do not comply with this provision of the standard.

Failure Report. Failure analysis reports can be generated by selecting the calibration standard, function and range within a specified date range. This report indicates which UUT where calibrated by the selected standard, grouped by individual Asset ID number, and the specific function, ranges, and test points affected.

Drift/Interval Analysis. Drift and Interval Analysis enables users to plot data and to analyze trends of measuring and test equipment, between calibrations, on a test point basis. This feature will allow users to determine optimum calibration intervals for their equipment. Drift analysis tracks and analyzes trends in laboratory standards and client M&TE between calibrations on a test point by test point basis. The Drift analysis module allows you to plot data, look for trends and calculate basic statistics. Ultimately, this tool will enable the laboratory to establish the uncertainty of its standards and client's M&TE in real time, to determine optimum calibration intervals for its equipment.

CPMS 50 may also incorporate advanced security features including; Comprehensive User Manager Detailed Audit Trail; and Selectable audit trail reporting. A User Manager allows the system Administrator to set user access, and permission levels within CPMS 50. Users' activities are automatically tracked and logged in the audit trail for database trace ability and compliance to 21 CFR Part 11 audit requirements.

Revision Control. Calibration data sheets and subsequent revisions can be maintained and controlled through CPMS 50 exclusive data sheet approval process. Data sheets are created in an ASCII file based format out side of the SQL database. Data sheets can only be inserted into a database by individuals authorized for data sheet approval. Upon review and approval, data sheets are e-signed, and time and date logged as new or a revision, as selected by the authorized individual. When a data sheet is revised, the old data sheet is inactivated, but maintained in the system, thus preventing the use of retired data sheets, and only allowing the currently approved data sheet for use.

Storage options. Typically, a Data sheet file contains all of the test point data, specifications, automation script commands, and calibration instructions for a single data sheet. A calibration file is a simplified version of a Data sheet file. No automation scripting or calibration instructions are stored. The calibration file also stores the UUT's measurement data. The calibration file can be either recalled into one of the UUT channels or reopened independently as a data sheet, with UUT measurement data.

CPMS 50 may also feature an automated cataloging system of all data sheets and calibration files. The catalog can be used to locate a data sheet or a calibration file. The data sheet catalog can be searched by model, manufacturer, equipment description or calibration procedure. CPMS 50 can also support barcode data entry for M&TE ID and Test Report numbers.

Data sheets can be created by any person with the prerequisite technical knowledge of the unit under test. The actual process of creating data sheets requires minimal training. Data sheets should be approved by the appropriate authorized individual before they can be inserted into the database for use. Data sheets are initially created in file format, and must be approved, and e-signed prior to submittal into the database. This process assures proper data sheet validation and approval in accordance with industry quality standards, and users quality procedures. Data sheet approvals are controlled by the customer, adequate controls should be in place for the review, acceptance and approval of data sheets prior to use.

Data sheet revision control. In further embodiments, Data sheets must not only be approved, their revision are also tracked and controlled. Upon approval of a new data sheet, CPMS 50 tracks previously created data sheets of the same number. If previous data sheets exist, the new data sheet can be added as a revision, or a new data sheet. CPMS 50 tracks old revisions and only allows the current revision for use.

The usual starting place for an automation script is a previously created data sheet. Having said that, scripting commands can be added to a blank data sheet if desired. The training requirements for script authors will vary with the nature of the scripts being written. If, for example, a mathematically intensive script is being written, the author must have the requisite math skills. As far as the actual scripting process is concerned, the direct relationship of data sheet rows and script commands keeps the process relatively easy.

All features disclosed in the specification, including the claims, abstract, and drawings, and all the steps in any method or process disclosed, may be combined in any combination, except combinations where at least some of such features and/or steps are mutually exclusive. Each feature disclosed in the specification, including the claims, abstract, and drawings, can be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features.

Also, any element in a claim that does not explicitly state “means for” performing a specified function or “step for” performing a specified function, should not be interpreted as a “means” or “step” clause as specified in 35 U.S.C. § 112.

TABLE 41 Mode Indicator Information conveyed “Myself” None Calibration Processor does not anticipate an instrument range assignment to this test point. This condition exists when no test point specifications are available or no Standards Synchronization parameters are available. (Silver square) Calibration Processor anticipates an instrument range assignment to this test point, but has not received one. This condition exists when test point specifications are available and Standards Synchronization parameters are available. (Green square) An instrument range is assigned and the test point and instrument range's calculated accuracies do agree within 0.1% of each other. (Red square) An instrument range is assigned, but the test point and instrument range's calculated accuracies do not agree within 0.1% of each other or Calibration Process Manger is unable to perform calculations using the data. “Def Stds” None Calibration Processor does not anticipate an instrument and “Stds range assignment to this test point. This condition exists Used” when no test point specifications are available or no Standards Synchronization parameters are available. (Silver) Calibration Processor anticipates an instrument range assignment to this test point, but has not received one. This condition exists when test point specifications are available and Standards Synchronization parameters are available. (Green) An instrument range is assigned and the test resulting test accuracy ration is >=4:1. (Red) An instrument range is assigned, but the test accuracy ratio is <4:1. (Fuchsia) An instrument range was manually assigned to the test point that the Calibration Process Manager can not use, but will store with the data sheet, as directed by the user. This condition exists when test point specifications are not available, Standards Synchronization parameters are not available, or Standards Synchronization parameters do not directly match the instrument range selected. This condition will most often occur when an instrument range is manually selected and is not a direct parametric match with the test point. As of this version, the Calibration Processor is not able to divine accuracy information from a combination of standards that indirectly comprise a parametric match with the test point. i.e.: The test point is measuring Ohms and a voltage source and current shunt are selected as standards. The manual assignments should still be made to facilitate instrument range utilization reporting and statistics, but the user is on his own for TAR and EMU calculations.
